Wireless and Satellite Handset  
Power-Management ICs  
General Description  
Features  
o 90% Efficient, 500mA Step-Down Converter  
The MAX886/MAX888/MAX1863 power-management ICs  
are complete power systems for wireless and satellite  
handsets. The devices operate from 3- to 6-cell  
NiCd/NiMH batteries or from 1- or 2-cell lithium-ion (Li+)  
batteries. They incorporate a high-efficiency, step-down  
DC-DC converter, a regulated 5V charge pump, and four  
linear regulators. The regulators supply power to the  
SIM, LCD, BB, DSP, and RF sections of a cellular tele-  
phone handset. The step-down converter and linear reg-  
ulator outputs are adjustable by internal 4-bit DACs,  
programmable through the I2C™-compatible serial inter-  
face. A pushbutton on/off scheme activates a 5µA low-  
power shutdown mode. The devices also feature a  
low-battery detector output and an internal startup timer.  
o Two 100mA DAC-Controlled LDOs  
One 200mA DAC-Controlled LDO  
One 20mA DAC-Controlled LDO  
o 3- to 6-Cell NiCd or NiMH Operation  
1- or 2-Cell Li+ Operation  
o +2.7V to +12V Input Voltage Range  
o 250µA Standby (PFM) Quiescent Current  
o 5µA Shutdown Current  
o I2C-Compatible Serial Interface  
o Selectable 375kHz, 535kHz, 670kHz, 925kHz  
(or Synchronizable) Switching Frequency  
The MAX886/MAX888/MAX1863 differ in output voltage  
range and power-on reset voltage. The MAX886 has a  
higher preset voltage range and is intended for 2-cell Li+  
or 5- or 6-cell NiCd/NiMH batteries. The MAX888/  
MAX1863 have a lower preset voltage range and are  
intended for 1-cell Li+ or 3- or 4-cell NiCd/NiMH batter-  
ies. All devices are available in a space-saving, 32-pin  
TQFP package.  
o Power-On Reset and Startup Timer  
o Thermal Overload Protection  
o Pushbutton On/Off Control  
o Space-Saving 32-Pin TQFP Package (9mm x 9mm)
